In this paper, a resilience enhancement method for power systems with high penetration of renewable energy based on underground energy storage systems (UESS) is proposed. Firstly, a resilience assessment model is established and the influence of extreme weather is quantified as the failure rate of power system components.
This study focuses on a safety evaluation method for underground gas storage. Gas storage is usually constructed underground in complex environments, and the service life of such facilities is limited. To ensure the secure and long-term operation of gas storage facilities, safety evaluation has beco

Abstract With the Paris Climate Agreement, the world faces the important task of reducing CO2 emissions to 95% below 1990 levels in 2050. In the Netherlands various measures are being designed for this task, including a transition from fossil fuels towards clean and sustainable energy sources, implementation of energy saving and efficiency measures,
As one of the most important underground energy storage infrastructures, underground gas storage (UGS) plays an important role in balancing supply and demand [1], [2], [3]. It makes important contributions in reducing carbon emissions [4], cleaner production [5], hybrid energy [6], and urban transportation [3].
An optimal design for seasonal underground energy storage systems is presented. This study includes the possible use of natural structures at a depth of 100 to 500 m depth. For safety reasons the storage fluid considered is water at an initial temperature of 90 °C. A finite element method simulation using collected data on the thermal

Underground energy storage has the potential to offer significant storage capacity for substantial energy quantity Developing rock caverns for hydrogen storage requires compliance with regulatory standards and environmental assessments. Safety protocols 43,
The aim of this paper is to provide a comprehensive analysis of risk and safety assessment methodology for large scale energy storage currently practices in
Underground hydrogen storage (UHS) is the injection of hydrogen into the geologic porous medium for subsequent withdrawal and reuse during off-peak periods to contribute to the energy mix. Recently, UHS has gained prodigious attention due to its efficiency for the storage of hydrogen on a large scale.
The underground siting of energy plants and related auxiliary facilities has been very often a viable opportunity for a large set of applications, outside as well as inside urban areas: in-cavern hydro plants, Combined Heat and Power (CHP) units, geothermal heat-pumps, facilities for Syngas production and CO2 storage.
Deep underground energy storage is the use of deep underground spaces for large-scale energy storage, which is an important way to provide a stable supply of clean

Underground (pure) hydrogen storage is a proven technology. Examples are found in salt caverns in the United States (e.g. Clemens Dome, Moss Bluff) and the United Kingdom (e.g.
This review examines the central role of hydrogen, particularly green hydrogen from renewable sources, in the global search for energy solutions that are sustainable and safe by design. Using the hydrogen square, safety measures across the hydrogen value chain—production, storage, transport, and utilisation—are discussed,
Shape design and safety evaluation of salt caverns for CO 2 storage in northeast Thailand Int. J. Greenh. Gas Control (2022) As one of the crucial carriers for large-scale deep underground energy storage, salt caverns have great prospects for development
Underground Hydrogen Storage (UHS) provides a large-scale and safe solution to balance the fluctuations in energy production from renewable sources and energy consumption but requires a proper and detailed characterization of the candidate reservoirs. The scope of this study was to estimate the hydrogen diffusion coefficient for
Large-scale underground oil storage has a great effect on national energy safety. China''s oil dependency has exceeded 70% for four consecutive years, so it is necessary for China to build strategic oil storage. The salt cavern is a good medium to store oil, and it is widely used in foreign countries.
Highlights. •. The bulk of Ontario''s energy supply is provided by wind or nuclear energy. •. The prevalence of these energies result in periods of surplus energy supply. •. This surplus energy can be stored as hydrogen gas to buffer supply and demand. •. Underground storage in geological media is explored for Ontario.
FECM has completed a multi-year study determining the viability, safety, and reliability of storing pure hydrogen or hydrogen-natural gas blends in different types of underground environments, allowing for much wider regional application. The global transition to a low
• Gas storage operators should begin a rigorous evaluation program to baseline the status of their wells, establish risk management planning and, in most cases, phase-out old wells with single-point-of-failure designs. • Advance preparation for possible natural gas
